UNITED STATES PATENT. OFFIC THOMAS J. PERRIN, OF DAYTON, OHIO.

ADJUSTABLE METALLIC WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 690,662, dated January7, 1902.

Application filed March 29, 1901. Serial No. 53,422. (No modell) To allwhom, it may concern.-

Be it known that I, THOMAS J. PERRIN, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Adjustable MetallicWindow-Screens; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in adjustablemetal windowscreens.

The object of the invention is to provide a window-screen of the abovetype which is capable of adjustments to fit different sizes ofWindow-frames and which may be manipulated by any one withoutdifficulty, it not being necessary to mark a screen for a certain Windowto which it might have been previously applied.

Referring to the accompanying drawings,

Figure 1 is an elevation of my improved adjustable window-screen. Fig. 2is a similar view of the lower portion of the screen with the lockingdevices omitted. Fig.- 3 is a detail view of a skeleton frame, showingthe sides bowed or curved before the stretching of the wire-cloththereon. Fig. 4 is a detail of a skeleton frame with wire-clothcomplete, showing the manner of attaching the cloth towire frame orskeleton. Fig. 5 is a top view of the sheet metal comprising the top orbot tom rail. Fig. 6 is a side view of the same. Fig. 7 is an edge Viewof the same. Fig. Sis a cross-sectional View on line w" m of Fig. 6.Fig. 9 is a top view of one of the side rails. Fig. 10 is a side View ofthe'same. Fig. 11 is a cross-sectional View on line 00 w of Fig. 10.Fig. 12 is a plan view of the metal blank before being formed into acorner-piece. Fig.

Fig. 16 isa view of a lower corner of the screen, showing a portionof a side ofthe window-frame. Fig. 17 is a view of the upper portion of theadjustable frame. Fig. 18 is a sectional view on line to w of Fig. 16;

Fig.- 19, detail views of-the locking-spring.

Fig. 20 is a sectional'view on lines; a: of Fig. 17; Fig. 21, asimilarview on line y y of Fig. 17.- Fig-22 is an enlarged Vertical Viewshowing more clearly how the corner-pieces are attached to thesiderails. Fig. 23 is a view of a corner of the skeleton frame and thewire-cloth united, showing-more clearly how said wire-cloth is securedto the skeleton frame.

Referring to Fig. 1, this form of screen is adjustable sidewise. 1 1designate metallic side rails, each of which has a'channel or groove 2.(Shown in dotted lines in Fig. 1; also shown in Figs. 11, 20, and 21.)

3 designates right-angled corner-pieces. In

Figs. 1 and 2 these corner-pieces telescope onto the side rails 1 1 andare made fast thereto, while they freelytelescope over the top andbottom rails 1 1 allowing theside rails 1 l to contract or expand,accordingto the size of Window-frame.

4 designates a portion of the side of a window-frame. secured to each ofsaid sides. These tongues are provided with notches 6, which cooperatewith spring-catches 7 to lock the screen at top or bottom. Theselocking-springs 7 are secured at 8 to the side rails and are stopped bypins 9. The lower ends of said springcatches are turned at angles to thebody of the springs. These ends enter the lockingnotches 6.

10 is a finger-piece which is secured to the spring-catches 7 andprojects out a sufficient distance to enable the' finger to catch holdthereof. I

11 designates a skeleton frame which may be made of any suitablematerial, either a round wire, channel, or angle-iron. This frame issprung together in a V-shaped notch 12 and is securely held in place bythe wire-cloth 13.

Fig. 3 shows the skeleton frame before stretching the wire cloththereon. Fig. 4. shows said frame with the wire-cloth stretched thereon.It will be noted that in Fig. 3 the frame bulges on four sides, while inFig. 4 the sides are straight. The straightening of the sides appliesthe necessary tension to the wire-cloth and prevents it from sagging at5 is a metallic tongue or guide gcther. As in Figs. 20 21, thewire-cloth incloses the frame 11 and is made secure there-.

to. It will be understood that the grooves 2 of the side rails receivethe tongues 5, and the screen is guided thereby in its perpendicularmovements.

Referring to Fig. 20, the corners 3 telescope over the side rails andare bent around in the groove 2 and meet in the center and are securedto said side rails.

In Fig. 21 the corners are telescoped similar to that shown in Fig. 20;but the edges fitting in the groove 2 are overlapped and made secure tothe side rails by a set-screw 15, thus allowing the top rail to beelevated or lowered. The top and bottom horizontal rails are wider inthe present case than the ordinary rails in non-adjustable screens. Thisis necessary in order to provide suitable room for the necessaryadjustments. The adjustments are obtained by lowering or elevating thetop rail after first having loosened the screws 15. This constructionenables a vertical adjustment of the screen.

The blank shown in Fig. 12 is used in the construction of the cornershown in Fig. 2i and is provided with an excess of metal, as at 16,which provides the overlapping edges in the groove 2. g

In Fig. 14, 17 designates adj ustiug-bars secured to the interior of thecorner-pieces by screws 18. The ends 18 of these bars are bent at rightangles and the inner or shorter end provided with means for securing adrawspring 19. 20 designates a similar bar bent at each end, also bentat 21 to receive the spring 10. One end of this bar 20 is secured to theinterior of the corner by the screw 18, as before described, and theotherends of said bars are supported in an operative position by a pinor stud 21. The spring 19 is secured to the end thus supported, so thatit will be seen the said spring 19 is connected to each of said bars.The function of these bars and the spring is to expand the side rails tocompensate for the difference in the width of windows, and thus thescreen will be held firmly in position.

It will be seen from the several views of the drawings, particularlyFigs. 20 and 21, that there is considerable space provided within themetallic frame composed of the side and top rails 1 1 1 1. This isnecessary in order to obtain the proper adjustments of said metallicframe,which adjustments may be obtained without afiecting thescreen-frame 11.

The slots 23 in the rails and the corner-pieces are just large enough topermit of easy adj ustments of the outer metallic frame withoutafiecting the wire screen or its frame. The outer metallic frame canreadily be opened and the inner frame and wire-cloth removed andreplaced whenever desired without inj ury to the frame or withoutchanging the frame in any manner.

Having described my invention, I claim- 1. An adjustable metallicwindow-screen, comprising side rails having longitudinal grooves thereinadapted to receive tongues or guide-pieces extending from the sides of awindow-frame, top and bottom rails, cornerpieces uniting the side railswith the top and bottom rails, the said corner-pieces fitting in thegrooves on the side rails, catches inclosed in the bottom corner-pieces,a tension-frame, wire-cloth secured thereto, said frame and cloth beinginclosed in the side, bottom and top rails, and means for expanding theside rails to maintain them in close contactwith the window -frame,substantially as specified.

2. In an adjustable metallic window-screen, an adjustable screen frameconsisting of side rails having longitudinal grooves therein, and topand bottom rails, corner-pieces having rigid connections with the siderails and telescopic connection with the top and bottom rails, atension-frame, a wire-cloth secured to said tension-frame, said frameand cloth being inclosed in the rails, and the said rails being adaptedto be adjusted inwardly and outwardly in order to increase or decreasethe dimensions of the screen, catches secured within the lower cornersof the frame and adapted to lock the screen in position, a finger-pieceprojecting from said catches on the interior of the screen, and meansfor maintaining the screen in rigid contact with the window-frame.

3. In an adjustable metallic window-screen, an outer metallic frame,telescopiccorners therefor, a screen and frame inclosed in said outermetallic frame, adj usting-bars, springs connected to said bars, saidadjusting-bars and springs being inclosed in the top and bottom railswhereby the sides of the outer frame are pressed outwardly to increasethe width of the screen, and means for locking the screen in position inthe window.

In testimony whereof I affix my signature in presence of two witnesses.
